The remote Apache Tomcat server is affected by an information disclosure vulnerability.
According to its self-reported version number, the Apache Tomcat service running on the remote host is 6.0.x prior to 6.0.53, 7.0.x prior to 7.0.77, or 8.0.x prior to 8.0.43. It is therefore, affected by a flaw in the handling of pipelined requests when send file processing is used that results in the pipelined request being lost when processing of the previous request has completed, causing responses to be sent for the wrong request. An unauthenticated, remote attacker can exploit this to disclose sensitive information. Note that Nessus has not attempted to exploit this issue but has instead relied only on the application's self-reported version number.
Upgrade to Apache Tomcat version 6.0.53 / 7.0.77 / 8.0.43 or later.
